“For me, philosophy, as an idea, means universal, and in a radical sense, ‘rigorous’ science. As such, it is science built in on ultimate foundation, or, what comes down to the same thing, a science based on ultimate self-responsibility, in which, hence, nothing held to be obvious, either predicatively or pre-predicatively, can pass, unquestioned, as a basis for knowledge. It is, I emphasize, an idea, which, as the further meditative interpretation will show, is to be realized only by way of relative and temporary validities and in an infinite historical process—but in this way it is, in fact, realizable.” (Husserl, 1989, p. 406) The preceding passage illustrates a number of interrelated themes which will be familiar to students of Husserl. He is dedicated to foundational science and places strong emphasis on the researcher’s self-responsibility. He asserts that the knowledge yielded by scientific praxis is perspectival and contextual, an insight linked to his vision of science as an open-ended, infinite task. If a psychological research method is to be genuinely termed phenomenological and Husserlian, then each of these themes, which also represent commitments on the part of the practitioner, must be present, implicitly or explicitly.
